Is there something we can trigger on to know that the calypso has booted? Can we look for a change in the serial port control lines?
I won't rely on the port control lines because they are not totally under control of the GSM firmware while booting (there is also the FLUID ROM bootloader). When the GSM firmware is up, it sends "AT- Command Interpreter ready" to the serial port. If CTS is high, the GSM firmware should set GPIO 1 to high when it tries to send this initial message. Maybe this can be used ? Best regards, Dieter
